Super technology leader

The take-off of the Yishan Super Rocket can not be described as "shaking the world".

That huge sound wave can spread far away!

That huge figure can let people watch it fly into the universe!

The huge tail flame also makes the infrared radar capture extremely clear!

Anyway, the Yishan rocket is directly connected with the word "huge", and no one doubts the name of the "Yishan".

Some people even feel: "It's okay to move the mountain without moving the mountain. If you blast the mountain directly, there is no problem at all. The effect is the same."

The moat becomes a thoroughfare!

Gravity and the atmosphere are the "trenches" between humans and space, and they are the "naturally formed ditch that obstructs traffic" for mankind to move toward the future. The emergence of rockets is a bridge between the "trenches" and larger and larger rockets. It represents a bigger and bigger bridge.

Tianxia people are very familiar with this. Tianxia’s geographical environment is too complicated. People live in the north and south of the sky. Therefore, Tianxia people build bridges, pave roads, pass ditches, move mountains, fill the sea, and pass through tunnels. Connected in series.

It is the same now. The Yishan rocket lifts off. It is the "cable-stayed bridge" of the space age, helping humans to communicate between the ground and space.

"Booster separation!"

The Yishan rocket is already flying very high. Although infrared tracking can be seen very clearly, the scene is not very friendly to the audience, so the audience is shown the rocket perspective.

When the booster is separated, the audience can see that the originally tight butt joint suddenly separates by a big opening, and the tail of the booster no longer emits flames, and then the motorized nozzle next to the booster slams outward, letting It quickly moved away from the carrier.

The vehicle flew upwards according to its inertia, and then the engine ignited at a high altitude and continued to push it to space.

Generally, it only takes a few minutes for a rocket from take-off to enter space, and the Yishan rocket is no exception.

When the carrier of the Yishan rocket entered space and climbed a certain orbit, the cargo hatch was finally opened.

Until now, people knew what was in it.

"Look at the look... it turned out to be the maintenance module?!"

"I thought I would launch the modules in the commercial area first. I didn't expect that the modules in the industrial area or the maintenance bays would be launched first."

"Ah, is there any problem, is there any particularity about this launch sequence?"

"It's okay. It depends on Navigator's plan. It's just that it skips the commercial area and launches directly into the industrial area. How does this maintenance cabin connect with the rotating simulated gravity cabin?"

"Actually, it's okay if you don't dock it. Humans haven't worked on a single space station. Just consider it a single space station. After the modules in each area are assembled, then they can be docked together."

"I guess the navigator intends to change paths, not to engage in business, and to start scientific research. In other words...with this maintenance capsule, humans can repair satellites in space, right?"

"What a different way? I suddenly thought of an advertisement. I don't know if any dear man posted it for everyone to see. This is also a very profitable industry."

"Come on, advertising slogan: high-altitude scrubbing, satellite surface dust removal, solar panel polishing and waxing, space station spray painting and renovation, space shuttle maintenance and replacement of three filters. Large quantities, cheap, and invoices. For details, please consult the leader of the space company Tang, Call 138...whatever behind."

"Hahaha, are all these years of funny jokes finally coming true? But why is your ad not complete, what about the front?"

"What's up front, Navigator is not an arms company. Aircraft carriers, submarines, nuclear warheads, and fighter jets have nothing to do with them."

"How do you know it's okay? You don't know the relationship between domestic aerospace science and technology and aerospace science and engineering. Navigator space station can be built, rocket can be built, lunar base can be built, orbital shuttle can be built, if you want, you feel that these things can be built What is it converted into?"

"His—I think about it carefully, I was shocked!"

Many years ago, there was a funny picture on the Internet. I forgot where the source was. Someone changed the brand P on the mobile tricycle into a "specialized aircraft carrier".

There is also a line of fine print below: Satellite dust removal and waxing, nuclear warhead oiling and refurbishment!

The actual sign originally read "fix leaks on the roof".

Because I thought it was very interesting, it spread, and the "items" became more and more supplemented, and finally it became a plain text mode.

But who would have thought that the waxing, oiling, and refurbishment of satellites that seem like a joke will be a highly profitable high-tech industry in the future. It is much hotter than it has only been in these years, and it is not too mature for repeated rocket launches. The project is promising.

First, this is because the current human rockets are still transportation vehicles that face high temperature, high pressure, and high-strength external impact. The one-time use of this transportation tool itself improves reliability.

Because of all the components, it only takes about 30 minutes to complete the task.

It is very difficult in itself to force a high-risk engine system to increase its reliability from a maximum of 30 minutes to 300 minutes or more.

Especially when the technology is insufficient.

In addition, the rocket itself has no actual economic benefits, and the ultimate purpose of the rocket's work is to launch a payload into orbit.

Including all satellites, spacecraft, space stations, deep space probes, etc.

This is the meaning of rocket work.

And all these ballistic flying objects can be regarded as various "artificial satellites."

The value of satellites, especially those large and heavy satellites, in most cases far exceeds the cost of the rockets that launch them.

For most heavy-duty satellites, even if the rocket that launches them can be repeatedly used 5 or even 10 times, it is not as economical as to make this satellite refurbished and used once.

Taking Tianxia’s most common rockets and satellites as an example, the international launch price of the Changsan B rocket is about 60 million to 70 million US dollars.

If the satellite platform launched is Dongfanghong-3, the price of Chengxing is about 200 million US dollars.

The price of a star based on the Dongfanghong-4 satellite platform may exceed 500 million.

The more advanced Dongfanghong-5 satellite platform even exceeds 1 billion US dollars.

This is a relatively cheap price. If you purchase similar satellites in the West, it may cost 1.5 billion US dollars.

Therefore, when a country purchases large-capacity synchronous communication satellites, the seller of the satellite simply "buys the satellite and sends it for launch."

The lifespan of a large-capacity communications satellite is 10 to 15 years, which is equivalent to one year consumption of 100 million US dollars.

If it can be refurbished and extend its life span by half or even two-thirds, it would be equivalent to creating a value of $500 to $1 billion.

And more than ten years have passed, science and technology must have taken a big step forward. At this time, it is not simply saving money to update its equipment and make it more suitable for current and future tasks.

Let alone how many rocket launches are enough to extend once, many people hesitate enough for the rocket launch "not 100% success rate" alone.

Yes, if the launch fails, not only will the money be raised, but the future needs of the country will also be raised.

The postponement of a satellite's launch may affect a country's development strategy for several years or even longer.

For example, some countries have bought a weather satellite and want to rely on this satellite to achieve autonomous weather forecasts and get rid of the weather forecast control of certain countries. Some countries in the province also carry private goods when providing weather data, but when these After the satellite launch failed, the next few years must be patient.

However, when "this satellite" is already in orbit in space, it's a different story.

As long as you don't actively slow down the satellite, and then let it quickly enter the atmosphere and burn down, it can stay in the earth's orbit for a long time.

If you replace it with parts and add some fuel at this time, so that it can be used like this year's satellite from ten years ago, wouldn't it be safe and advanced?

And there is a better way.

Country A has no satellites in space and cannot be upgraded, so country B can even repair and upgrade the orbiting satellites of its own country and sell it directly to country A in space!
